Aston Merrygold’s stepdad has hit back at critics of JLS’s debut album, saying people don’t give them enough credit.

Oz Merrygold, who has looked after Aston (pictured left) since he was three, heard the band’s self-titled album being reviewed on Victoria Derbyshire’s show on BBC Radio 5 Live.

Hurt by comments his stepson’s band might be ‘a flash in the pan’ he emailed in to protest and then gave his opinion on air.

He said: “I just wanted to defend the boy a little bit – some of the comments were a little bit less than complimentary and, after everything they’ve achieved, I just wanted to fight their corner.”

Oz said that JLS – who came runner-up to Alexandra Burke on last year’s X Factor – should be applauded for writing many of the songs on the album.

He said: “They’ve written nine of the songs on the album… I don’t think people give them enough credit or realise quite how good the boys are musically.

“They don’t just sing, they produce their own stuff, write their own songs so that quality will help them stand the test of time. They will mature.

“I know people liken them to Take That but some of Take That’s first songs weren’t that great or that memorable and they matured and their music improved. They will stand the test of time and their music will get better and better.”

But Oz added that though he liked music, he was more a fan of bands such as Foo Fighters rather than boy bands.
